答案：【高分范文】Dear Mike,I am writing to express my great appreciation for your timely help and assistance when I had difficulty in writing my essay on African American women writers.Without your constructive suggestions and warm encouragement, I wouldn’t have finished my paper so soon. First and foremost, whenever I was stuck on what to write, it was you that discussed with me and gave me the invaluable inspiration. There were so many days and nights when you accompanied me to pace back and forth in the library, trying to define a topic, sort through my thoughts and then choose the arguments. Furthermore, I got so many useful references because you taught me how to use specialized search engines to get results from scholarly literature, such as theses and academic publishers. Last but not the least, your encouragement gave me a big boost and it reminded me that I was moving in the right direction.You have been so kind and helpful since we knew each other. I would like to convey in this letter my heartfelt thanks to you again. I wish our friendship can last forever. Although we will graduate from the university soon, I will always be there for you no matter what happens, just like what you have done for me.Yours sincerely,Tom
